I read a long tine ago here on the Ford Barn. If they wont come apart by soaking them, and you want to get them apart.

Build a fire in your Charcoal BBQ, and place them the Coals for about 4 Hours. After let them cool by themselves at least 6 hours.
When I wintered up North, I had a Wood Furnace, I would place a couple in the fire box over night, then let them cool as above. Every one I put in the fire came apart, 10 of them. The Fire did not hurt the Insides.
Try it, it works, you are going to rebuild them anyways.

PS; I forgot to add, bury them in the coals, and rotate them once in a while.
